Astro-Sinker is one of several Mini-Cons employed by the Decepticon bounty hunter Astrotrain. The middle child of the Sabotage Team, he makes sure his brothers' scams run smoothly—and if that means killing somebody, he's fine with that. Uncomfortably fine with that.
- Astrotrain (Multi-pack, 2007)
- A redeco of the Giant Planet Mini-Con Team member Deepdive, Astro-Sinker transforms into a submarine of undetermined model. This mold is one of the few Mini-Con molds to have a Powerlinx peg as well as socket. He was only available as part of the Astrotrain set (which also came with Starcatcher, Astro-Hook and Astro-Line), the first toy set exclusive to the Fun Publications Official Transformers Collectors' Club.
- Astrotrain's mini-con trio are named in homage to Hook, Line, and Sinker, the servants of Unicron from the U.S. Marvel comic.
